A stern tube, which is present at the bottommost part of the ship, connects the engine, inside of the ship to the propeller outside. During cruising at sea, up to 3.5 MW of electric power is extracted from the ship's main diesel engine/ propeller shaft (90,000 hp per ship) via a salient pole shaft generator, which is fitted to the main propeller shaft. The hub has a coupling piece with a cam on the front, which indicates that the propeller could be disconnected without pushing the propeller shaft into the ship. The main function of the propeller shaft is to turn the propeller. The part that requires the most amount of time and thought is the ship's propeller, the piece of equipment that propels the ship forward.

In this condition, Gap and Sag values as prescribed by the maker are set between the aft flange of the intermediate shaft and the propeller shaft forward flange by adjusting the supports/bearings on the intermediate shaft. Image of stern tube and propeller shaft in a lighthouse ship. The stern tube contains the propeller shaft where it passes through the hull structure. In my marine school days there were some quite esoteric designs, but the ones below are the most relevant today. Section design and the number are determined by the shape of the hull, the length of the propeller shaft and the operational features of the vessel.
